==== Ribosomal RNA ====

Ribosomal RNA (rRNA) is the primary constituent of [[ribosome]]s. Ribosomes are the protein-manufacturing [[organelle]]s of cells and exist in the [[cytoplasm]]. rRNA is transcribed from DNA, like all RNA, and in eukaryotes it is processed in the [[nucleolus]] before being transported through the [[nuclear membrane]]. This type of RNA makes up the vast majority of RNA found in a typical cell (~95%). While proteins are also present in the ribosomes, the [[Svedberg|23s]] rRNA forms the active site for peptide bond formation, making that molecule a [[ribozyme]].
